MCU I/O Solution
Actt MCU I/O solution is especially suitable for ultra-low power MCU applications. It can easily support 1.2V core voltage power off, and voltage transformation between different voltage domains. The common GPIOs contain not only digital functional cells, but also analog input/output cells. The internal latches low power design can help to decrease the leakage current greatly while 1.2V core voltage powers off.
There are also a wide variety of interrupt I/O for customers to easily communicate with outside world at low power states. The powerful level shift structure can help customers use fixed internal I/O voltage, but unfixed power voltage for the outside interface.
